METAL STRUCTURAL MEMBER AND BUILDING CONSTBUG'IIOR.

Specification of Lettcrl Patent.

Patented Jan. 9, 1917.

Application filed Kay 8, 1916. Serial No. 98,084.

To all whom it may concern Be it known that I WILLIAM C. Eowanus, Jr., a citizen of the llnited States, residing at Kansas City, in the count of Jackson and State of issouri, have invented certain new and useful Improvements in Metal Structural Members and Building. Construction, of which the following is a description, referring to the drawings, which form a part of this specification.

The invention relates particularly to a composite metal structural member or stud and its uses in combination with plaster board or other covering material for partition, wall, ceiling and like building construction. The principal objects of the in vention bein to fabricate metal structural members which shall combine strength with lightness of weight; to afford means for permanently attaching and combining therewith such covering ma erial as laster board for the purposes and u .es inci ent to building construction; to eliminate danger of damage to such metal structural members in transit and insure easy handling and erection thereof in building operations, and to permit ofan optional arrangement of the plaster board with respect to the fastening means.

Various types of fabricated sheet metal studding have been devised having clips or other fastening means projecting from the faces of the stud for supporting metal lath, plaster board or other covering material. These projecting clips get mashed in shi ment, make the studding diflicult to handle in manufacture, trans ortation and erection and bein spaced at xed distances do not permit any flexibility in the arrangement of the covering material with respect to the studding.

It is very essential in plasterboard partition construction that the laster boards be so staggered upon the studding that vertical joints are broken, also that the corners and edges of the plaster-boards be thorou hly anchored to the studding, otherwise cracEing of the applied plaster will occur.

In my invention, the fastening member is not a component part of the fabricated stud but can be attached to the stud during the erection of the partition; the studding is symmetrical and each fastening member being reversible end for end in the studs the final fixed position and arrangement of such fastening member, with respect to the stud- 'the application view in perspective of a transverse tie mem-' ding and plaster-board, is left optional with the erector of the partition.

In the drawings: Figure 1, representing a view in perspective of a partition, illustrates of my invention. Fig. 2 is :1

her or fastening means. Fig. 3 is a view in perspective of a channel element as used in the manufacture of the composite structural I-beam. Fig. 4 is a view in perspective of the composite structural I-beam. Fig. 5 is a sectional view taken along the line X-X through the web of the I-beam seen in Fig. 4. Fi 6 is a sectional view taken along the line 1Y through a stud and fastening member in Fig. 1.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

Referring to the drawings: in Fig. 1, a series of vertical composite I-beam studs 10 are shown seated in a base channel runner 11 and covered by an inverted top channel runner '12, these runners in actual building operations being secured to floor and ceiling, or otherwise employed as desired, to give the required alinement to said studding. Each I-stud 10 is composed of two channel-like members 13, 13 placed back to back. A plurality of transverse de ressions or flat bottomed grooves 14 are ormed at spaced 1ntervals across the back face of the web 15 of the channel-like member 13. In Figs. 4 and 5, these grooves, 14, 14 in the webs 15 of the two combined channel-like members 13, 13 are seen to aline thereby forming a plurality of transverse slotted o enings 14 extending from face to face of t e composite I-beam 10 and the web portions be-' tween such slots 14 are in contact and are rigidly welded or riveted together, as at 16.

In Fig. 1 the plaster board 17 is secured to the studding 10 by means of transverse tic members 19 formed preferably from sheet metal strips. The central body portion of the tie member 19 is approximately of equal rectangular cross sectional area to the slot 14* in the stud 10. The tie mem-' ber 19 has a pair of prongs 20, 21 at one end and a single prong 22 and a shoulder prong 23 at the opposite end. The prongs 20, 21 and 22 He in the plane of the central body portion of 19 while the shoulder prong 28 is bent at right angles thereto. The workman erecting the partition inserts the paired prongs 20, 21 into any selected slot 14" from tie member.

either face of the stud at his election and pushes the transverse tie member through same until the shoulder prong or head 23 contacts the flange 2 1 of the channel 13 as seen in Fig. 6. The prongs 20, 21 and 22 new project from the opposite faces of the I-stud 10, and the sides of such combined depressions 14, 14 being rigidly secured by the welds 16, 16 as seen in Fig. 5 positively prevent slipping of the tie member 19, sidewise between the composite Web portions 15, 15 and the shoulder head 23 positively prevents further inward movement 0 the Movement of the tie member 19 from the position seen in Fig. 6 can only occur in one direction, that is it might be withdrawn from slot 14* by a pull on prong 22. As illustrated in Fig. 1, the finished portion of the partition shows the prongs 20, 21 bent over upon and securing the ends of adjacent plaster boards to the studding also the prongs 22 are seen penetrating and clenched over upon the central portion of the plaster-board 17, which has been driven upon the prongs 22, whereby the weight of the plaster-board and applied plaster coating is carried primarily b the studding. The tie member 19 is fina ly anchored in place when the prongs 20 and 21 are bent over upon the plaster-board.

As has been stated above, the paired rongs' 20, 21 may enter a slot 14: from either face of the stud. This permits of the staggering of vertical joints between boards, since the penetrating prong and the shoulder head 23 can be located on either face of stud and in any desired slot 14*. It is not absolutely necessary to place tie memhere in all slots 14*,b'y forming aplurality of such slots 14 at convenient intervals in the web, the erector of the partition is enabled to select the most suitable spacing of tie members to pro erly secure the corners and edges of each oard and also to work in fractional boards as well as full sized boards and thus secure a more perfect structure.

Before attaching metal lath to the studdingi the prong 20 as seen in Fig. 6 is preferab y first bent at r-i ht angles or against the face of the stud us taking a position similar to the shoulder prong 23, this firmly anchors 19 againstmovement and leaves the po nted rongs 21 and 22 for attaching the metal ath. V

Such modifications may be employed as lie within the scope of the applauded claims. Havm fully described t 0 principles embodie in my invention what I nowclaim as new and desire ent-is:
